MANUFACTURE OF FLOOR-COVERINGS AND PLASTIC WALL AND CEILING FACINGS.

' SPECIFICATION forming part of Letters Patent No. 773,427, dated. October 25, 1904.

Application filed March 2, 1904. Serial No. 196,201. (No specimens.)

To a, whom it play concern:

Be it known that LGnoRe RUDoLF ScHMITT, engineer, a subject of the German Emperor, residing at Plinganserstrasse, Munich, Kingdom of Bavaria, in the Empire of Germany, have invented an Improved Manufacture of Floor-Coverings and Plastic Wall and Ceiling Facing-s, of which the following is a specification. I

This invention relates to an improved method for manufacturing linoleum-like floorcoverings and plastic lincrusta-like wall and ceiling facings, and dili'ers from the methods hitherto known by the use of waste pulp as a substitute for the ground cork, which, as is well known, is expensive. The waste pulpis found in paper and cellulose factories, in wood-grinding mills, and similar industrial establishments and was hitherto used solely for the manufacture of inferior quality cardboard or the like or.for manufacturing papiermach articles, as described and claimed in my pending application for United States patent of same date Serial No. 183,963.

In order to carry out my process, I proceed to describe it by way of a distinct example.

About onehundred parts, by weight, of the well-known linoxyn are mixed with about thirty-five parts, by weight, of resin and four parts, by weight, of turpentine and heated until a thorough solution and the formation of a gum-like mass or pulp are obtained. During constant stirring and heating there is added about one hundred and fifty parts, by weight, of waste pulp which contains about twenty per cent. of water.

It is not necessary to dry the waste pulp, as it can be used in the same condition in which it leaves the paper-factory. After being intimately mixed a pliable glutinous mass or pulp is obtained, which by the addition of a backing material can be made up into thin slabs, strips, or the like if it be desired to manufacture floor-coverings, or which, if

viz., December 5, 1903,

flexible Wall and ceiling facings are to be manufactured, is pressed into the requisite molds of wood, metal, and the like. In the latter case the mold is slightly moistened with water, and the already cooled but still pliable pulpy mass is then spread uniformly upon the said mold. After applying a sheet or strip of paper as a covering for the back or some similar material to which the pulp will adhere and which will prevent it from losing its shape when taken out of the mold the mass is left to itself for a time, after which the finished product is unrolled from the mold and dried.

As compared with linoleum and lincrusta articles hitherto made with ground cork those 7 made according to the present invention are much cheaper.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. As a new article of manufacture, a floorcovering consisting of linoxyn, resin, turpentine and waste paper-pulp. I

2. As a new article of manufacture, a floorcovering consisting of linoxyn, resin, turpentine and waste paper-pulp containing twenty per cent. of water.

3. As a new article of manufacture, a floorcovering consisting of one hundred parts by weight of linoxyn, thirty parts by weight of resin, thirty parts by weight of turpentine and one hundred and fifty parts by weight of Waste paper-pulp.

4. As a new article of manufacture, a floorcovering consisting of one hundred parts by Weight of linoxyn, thirty parts by weight of resin, thirty parts by Weight of turpentine and one hundred and fifty parts by Weight of Waste paper pulp, containing twenty per cent. of water.

5. A method of manufacturing floor-coverings and wall and ceiling facings consisting in mixing and heating Waste paper-pulp with linoxyn, resin and turpentine and then Working the mass thus obtained into slabs, strips or the like.

6. Ainethod of manufacturing floor-coverings and Wall and ceiling faeings consisting in mixing and heating Waste paper-pulp containing twenty per cent. of Water with linoxyn,

resin and turpentine, and then Working the I mess thus obtained into slabs, strips or the like. I0

In Witness whereof I have hereunto set my hand in presence of tyyo Witnesses.
